In ".env", I configured "UPLOAD_FILE_SIZE_LIMIT=100".
It seems that this configuration is only related to the knowledge base and Agent.

I just need a method that allows for larger plugin files to be uploaded.
Thanks for your reply and help.

Thank you.
Change the value of PLUGIN_MAX_PACKAGE_SIZE. It has been solved.
